This is just awful! Three men have been arrested in Sweden after a Facebook Live video allegedly documented them raping a young woman on Jan. 22. The sexual assault was reportedly streamed live to a private Facebook group, and police are investigating as we speak. Get all of the shocking details right here.

Swedish authorities have been asking people who were able to access the alleged Facebook Live assault to turn footage over to authorities, the New York Times reported via Swedish newspaper Expressenon Jan. 23. “Police and prosecutors have access to some of the images and video footage,” Magnus Berggren, a prosecutor in Uppsala, Sweden said of the alleged video, which may have been seen by hundreds of people. “What we do not have access to is the segment showing the actual assault.” So frightening.

Police reportedly arrived at an Upsala apartment around 9:00 AM on Jan. 22 after receiving multiple calls reporting “a rape in progress that was being streamed live to a closed group on Facebook”, according to Expressen. Three men aged 18, 20 and 24 were reportedly arrested on site.

“We are gathering evidence, technical evidence, but also interviewing,” Berggren also said. “We have questioned a number of people and there will be more interviews.”

Police spokeswoman Lisa Sannervik also told Swedish news agency TT that there are likely copies of the alleged stream. “Many have seen this on the internet, and we are eager to prevent any spreading of the movie,” she said.

Finally, Facebook spokeswoman Christine Chen tells HollywoodLife.com:

This is a hideous crime and we do not tolerate this kind of content on Facebook.

We take our responsibility to keep people safe on Facebook very seriously. Our Community Standards regulate what kinds of content can be shared on Facebook. Our teams work around the clock to review content that is being reported by users and we have systems in place to ensure that time sensitive content is dealt with quickly.

The vast majority of people are using Facebook Live to come together and share experiences in the moment with their friends and family. But if someone does violate our Community Standards while using Live, we want to interrupt these streams as quickly as possible when they’re reported to us. So we’ve given people a way to report violations during a live broadcast.

We also support local law enforcement who make data requests related to criminal investigations, and respond to valid requests relating to criminal cases.
